Abstract

The invention relates to a method for extracting soluble dietary fibers from fermented wine residues of aronia melanocarpas. The method comprises the steps; pretreating the fermented wine residues ofaronia melanocarpa to obtain wine residue powder; taking the wine residue powder and purified water, and evenly stirring them to obtain a wine residue solution; regulating the pH of the wine residue solution to 0.5-2.5, the leaching temperature to 60-100 DEG C and the leaching time to 30-70 min, and taking supernate after centrifugation to obtain a crude extracting solution; concentrating the crude extracting solution in a rotary evaporator with the vacuum of 0.1 MPa, the temperature of 60-70 DEG C and the rotation speed of 60 r/min to obtain a concentrated solution; and adding the concentrated solution into absolute ethyl alcohol for alcohol precipitation, taking a precipitate after centrifugation, and executing drying to obtain the soluble dietary fibers of the fermented wine residues ofaronia melanocarpa. According to the method, the fermented wine residues of aronia melanocarpas fruit wine are resourcefully utilized, and a new way is provided for the development of the soluble dietary fibers.

Description

technical field [0001] The invention belongs to the technical field of food, and in particular relates to a method for extracting soluble dietary fiber from fermented wine dregs of Aronia adenocarpus. Background technique [0002] Aronia adenocarpus fruit is rich in a large number of nutrients and bioactive components, such as dietary fiber, carbohydrates, proteins, organic acids, vitamins, minerals, proanthocyanidins, anthocyanins, flavonols and carotene. It has strong anti-oxidation, anti-bacterial and anti-inflammatory effects, and can be used to protect the liver, balance blood sugar, nourish the heart, prevent and treat diabetes, prevent and treat cancer, and treat diseases of the digestive system and cardiovascular system. [0003] In September 2018, Aronia black fruit passed the review of new food raw materials by the National Health Commission and became a new food raw material. At present, the research and development of Aronia nigra are all focused on the manufact...
